SURFACE PROTECTION
SYSTEMS FOR CONCRETE
Ready-to-use flexible
liquid membrane with
fibres for continuous
waterproofing layers
on exposed surfaces
WHERE TO USE
For waterproofing and protecting:
• flat roofs;
surfaces. Once dry, Aquaflex Roof forms a strong,
flexible, tack-free coating, suitable for occasional light
foot traffic.
• paving slabs;
Due to its flexibility, Aquaflex Roof is compatible with
normal dynamic expansion and contraction stresses
caused by temperature variations and vibrations.
• cupolas and curved roofs.
Once the substrate has been prepared (see relative
preparation section) Aquaflex Roof may be used on:
• ceramic and stone coatings;
• cementitious screeds and screeds made using
special binders (Topcem and Topcem Pronto);
• concrete;
• existing bitumen sheaths;
• wooden trimmings;
• galvanized sheet, copper, aluminium and iron.
TECHNICAL CHARACTERISTICS
Aquaflex Roof is a ready-to-use coloured
waterproofing product for external applications made
from synthetic resins dispersed in water, and when dry
forms a continuous, flexible, waterproof membrane.
Aquaflex Roof is resistant to all atmospheric conditions
and UV rays, and guarantees long-lasting protection for
the substrate.
Aquaflex Roof is easy to apply using a long-haired
roller, brush or spray on horizontal, sloping and vertical
Aquaflex Roof complies with the principles defined in
EN 1504-9 (“Products and systems for protecting and
repairing concrete structures: definitions, requirements,
quality control and conformity assessment. General
principles for the use of products and systems”) and
the requirements of EN 1504-2 coating (C) according
to principles PI, MC, RC and IR (“Concrete surface
protection systems”).
RECOMMENDATIONS
• Do not use Aquaflex Roof if the temperature is lower
than +5°C or higher than +35°C, or if rain is imminent.
• Do not apply if there is dew on the substrate.
• Do not apply Aquaflex Roof on substrates with a
residual humidity level of > 2.5% or on substrates
with rising damp.
• Apply Aquaflex Roof on surfaces without
depressions or hollows and, where required, with the
correct amount of slope.
• Do not apply Aquaflex Roof on weak or dusty
substrates.

• Do not apply Aquaflex Roof on painted
metal substrates.
• If it rains between one coat and another
of Aquaflex Roof, wait at least 12 hours
before applying the next coat, and only if
there is no residual moisture, otherwise
adhesion between the two coats could be
affected.
• Do not use on bituminous membranes
that have only recently been applied
(< 6 months). Always wait until the surface
to be treated has completely oxidised.
APPLICATION PROCEDURE
Preparation of the substrate
All substrates, whether they are new or old,
must be solid, clean, dry and free of all traces
of oil, grease, old paint, rust, mould and any
other material which could compromise the
bond.
Cleaning a substrate
before applying
Aquaflex Roof
Concrete and in general mineral substrates
must be solid and dry with no rising damp.
Any loose parts must be removed. Any
hollows in the surface must be repaired with
Planitop Fast 330 or Adesilex P4.
Prime the surface with a coat of
Aquaflex Roof diluted with 10% of water.
All wax, water-repellent treatments, etc. must
be removed from the surface of ceramic
substrates with a suitable detergent and/
or by sanding. On old ceramic floors with
gaps in the joints between the tiles, grout
the joints with Adesilex P4 before applying
Aquaflex Roof. Apply Eco Prim Grip on nonabsorbent ceramic substrates, while on any
other type of substrate apply Aquaflex Roof
used as primer diluted with 10% of water.
If applied on existing bituminous membranes,
carefully hydro-blast the surface, wait until
the water has drained off and treat the
surface with Primer for Aquaflex.

terracotta floor requiring
treatment before
applying Aquaflex Roof
When applying the product on metal
substrates, thoroughly clean the surface and
apply a coat of Eco Prim Grip primer.
Before applying Aquaflex Roof, pay
particular attention to the expansion joints
and the fillets between horizontal and vertical
surfaces, which must be waterproofed using
Mapeband SA, self-adhesive butyltape,
Mapeband or Mapeband PE120 bonded
to the substrate with Aquaflex Roof.
Structural joints must be waterproofed
with Mapeband TPE bonded in place with
Adesilex PG4. Use a suitable kit from the
Drain range to seal any drains.
Preparation of the product
The product is supplied ready to use. It is
however recommended to mix the contents
to perfectly blend the product.

Aquaflex Roof
Application of the product
Aquaflex Roof must be applied with a
long-haired roller, brush or airless spray.
Apply two dry coats of Aquaflex Roof
approximately 0.4-0.5 mm thick each. Wait
until the first coat is completely dry and that
it becomes slightly darker in colour before
applying the next coat. The second coat must
be applied in a criss-cross direction to the
previous coat (after approximately 8-12 hours
under normal temperature and humidity
conditions, according to the absorption of
the substrate). The dry thickness of Aquaflex
Roof must never be less than 0.8-1 mm.
If the substrate has micro cracks, insert
Mapetex 50, non-woven polypropylene fabric
between the two layers of Aquaflex Roof.
Spread on a generous coat of Aquaflex Roof.
Gently lay Mapetex 50 on the first layer of
Aquaflex Roof while it is still fresh and press
it down with a flat trowel or spiked roller so
that it makes perfect contact.
Spread on a second coat of Aquaflex Roof
once the first coat is completely dry.
Protect the Aquaflex Roof membrane
from rain until it is completely dry.
Cleaning the tools
Tools must be cleaned with water
immediately after use.
CONSUMPTION
Waterproof membrane: at least 2 kg/m².
Protective finish on bitumen membranes:
– approx. 0.5 kg/m² on smooth membranes.
– approx. 0.9 kg/m² on mineral-filled
membranes.
The consumption rates indicated are for a
seamless film on a flat surface and could be
higher on uneven substrates and according
to the absorbency of the substrate.
PACKAGING
20 kg and 5 kg drums.
